Is ultrasound a better preg-check?

Use of ultrasound extends the ability of veterinary practitioners performing reproductive examinations of cattle. The most common advantages cited are enhanced differentiation of ovarian structures, more accurate fetal aging and the ability to determine the sex of a fetus. Some fetal malformations may also be detectable using ultrasonography. While use of ultrasonography may be advantageous, it is usually more costly than traditional rectal palpation, and the benefits of using ultrasound diagnostics must be great enough to offset the higher costs.
